This study aimed to find effective policies to cope with low birth rate in local authorities. It was analyzed the variables-a number of child-care facilities, paid parental leave, labor force participation, and total working hours-using panel analysis from 2005 to 2014. The results were as follows. First, after testing the whole years, we found that the fittest model was the fixed-effects model of 2 models(fixed-effects model, random effects model). A number of child-care facilities had positive effects, and a number of child-care facilities, and total working hours in women influenced negative effects on total fertility rate. Second, during the former time and the period of plan for low birth rate and aging society, a number of child-care facilities influenced negative effects on total fertility rate. Third, a number of child-care facilities had negative effects on total fertility rate in Busan, Daegu, and Kwangju. Paid parental leave influenced positively on total fertility rate in 5 cities and a province. Women's total working hours were a significant variable of total fertility rate in Jeju. This study found that the variables which influenced on total fertility rate were different by local authorities, and a number of child-care facilities and paid parental leave were very important variables on total fertility rate.

The budget for public buildings is expected to increase to their maintenance, and the systematic maintenance and sufficient budget are recognized as the important factors for building maintenance. In Korea, buildings are not systematically maintained due to the lack of manpower, expertise and basis of maintenance budget estimates. Compared with Australia where the facility maintenance is optimized through asset management, Korea has only passive maintenance systems that focus on regulations. The introduction of the systematic asset management is required to ensure the advanced building maintenance in Korea. In this study, the asset management processes for social infrastructure facilities in and out of Korea were analyzed, and the asset management framework for public buildings were established. The asset management procedure consisted of ordinary asset management procedure, selective asset value assessment. The framework in this study was developed focusing on the asset management task for public buildings and presented the detailed contents of each step. The application of this framework to the actual work will enable the systematic management of building's value and performance, and the efficient appropriation of the maintenance budget.

Social welfare facilities where provide the socially disadvantaged with proper social services, face financial difficulties. This is because not only of the lack of governmental support, but also of social welfare facilities' lack of skills in developing abundant resources from the private sector. In this context, this study tried to find factors affecting resource mobilization of the social welfare facilities to devise policies in resource development. Mail survey was conducted with the structured questionnaire. Employees in charge of community resource development were asked to answer the questionnaire. The study population were two types of welfare facilities: community welfare centers and residential care facilities. A total of 293 community welfare centers and 632 residential care facilities responded to the survey. The response rate was about 62%. The dependent variable of the study was the amount of resource mobilization in the year 2001 which was measured as the number of donors, the total amount of donation, and estimated amount of gift-in-kind. Three types models were constructed per each welfare facility. Independent variables were selected based on the previous research findings: community environment factor, structural factor, and resource development factor. Multiple regression was utilized to analyze the data. The resource development factor turned out to be significant variable in various models. In the models of donors, the amount of donation, and the amount of gift-in-kind, at least one out of four variables in the resource development factor was significant. Welfare centers which establish the resource development department or hire employees to take care of resource development, and adopt computer software in managing donors, receive more donations than their counterparts. Interestingly, the centers where employees take the responsibility of resource development as well as other responsibilities (dual duty), did not have more resources mobilized than those with no employees for resource development. Using computer software in managing donors turned out to be a significant variable in many models, except for the donor model. In addition, residential care facilities located in urban area have more donors and donations, and among residential facilities those for the elderly, children, and the mentally retarded and those hiring more employees, receive more donations than those for the disabled and those hiring less employees. As for the gift-in-kind model, the centers located in high income area and residential facilities for the elderly, women and mentally retarded receive less gift-in-kind than those for the disabled. Based on the above findings, this study suggested that to mobilize resources the welfare centers as well residential care facilities need to have community resource development department or resource development staffs, and adopt computer software to systematically organize donors.

This paper analyzes the duration of the construction document (CD) phase of 42 large public building projects delivered by the total solution service of Public Procurement Services in Korea from 2009 to 2014. The quality of construction documents significantly affects the quality of construction and facility management. Thus, securing appropriate time for the CD phase during project planning is important for the quality of a project. Currently, the duration of the CD phase is planned based on the construction costs of a project following a notice of the Ministry of Land, Infrastructure and Transport. However, our analysis results showed that the correlation between the actual duration of the CD phase and construction costs is very weak. The actual CD phase takes 1.33-1.79 times longer than the planned duration. The practitioners who were interviewed, were already aware that the correlation between the duration of the CD phase and the construction costs is weak. They identified the complexity of the project, the extent of the design changes, project type, client characteristics, and others as more influential factors on the CD phase than the construction costs. To improve the quality of CDs, a new guideline for determining an adequate CD phase duration should be studied and developed.

Various slope protect systems are applied to the slope located around the major facility to maintain stability, and the applied these systems play an important role in protecting the structure by ensuring the safety of the slope. Reinforcement techniques ensure complete safety at the time of application to the slope, but over time, it may become difficult to secure safety. In particular, the deterioration of reinforcement systems may significantly reduce the stability of the slope. Therefore, it is necessary to secure the safety of the slope by defining the necessary items for maintenance of the protect systems and verifying them by the field expert. In this study, a group of experts were formed to determine these items and select their importance among them, and based on their data, the importance of each item was selected by Analytic Hierarchy Process (AHP). The selected items are expected to play an important role in the maintenance of reinforcement systems applied to the slope based on the survey items used by experts.

Ammonia emission from swine production process originates from three major sources: manure storage facility, swine housing, and land application of manure. Most of the ammonia gas that are emitted from swine production operations is the by-product of aerobic or anaerobic decomposition of swine waste by microorganism. Knowing the ammonia emission rate is necessary to understand how management practices or alternative manure handling process could reduce impacts of this emission on the environment and neighbors. Ammonia gas emission from pig slurry is very difficult to predict because it is affected by many factors including wind speed of slurry surface, temperature or pH of the swine slurry, sort breed differences and classes, and diets. This study was carried out to effects of pH and temperature on ammonia gas emission from growing-finishing pig slurry. Treated far slurry in this study were pH and temperature. Results showed that pH of slurry variable changes 5, 6, 7, 8 upon an addition of NaOH and $HNO_3$, respectively. The temperature of the slurry which was contained in a water bath maintained at increasing levels ranging from 10 to $35^{\circ}C$. Ammonia emission rate of influenced pH and temperature such that the increase in pH or temperature resulted to an increase in ammonia emission. The ammonia gas was not detected at pH 5 and 6. Moreover, at a slurry of pH 8, the ammonia ranged from 28 to 60ppm and 8-29 ppm at slurry pH of 7 while temperature was 13 to $33^{\circ}C$. When slurry pH was>6, the ammonia emission was significantly increased according to rise in temperature in contrast to acid treatment of the pH. There was also a significantly increase in ammonia emission relative to slurry pH of 7 to 8. The above findings showed that to effectively reduce ammonia emission from slurry of growing-finishing pigs, the pH and temperature should be maintained a low levels.

The purpose of this study is to classify and assess the characteristics of urban Korean parks by on-site park users' reactions, such as satisfaction, preference and cognitive image of the park and park facilities. The park facilities are classified into five types of satisfaction: management status, activity facilities, convenient facilities, circulation and density, and landscape facilities. The park users are satisfied with conversation, rest and relaxation in the parks, but not satisfied with studying and nature experience. The behaviors in the park are classified as park activities, emotional and experiential activities, and nature activities. The results indicate that the images of the parks are stable, comfortable and natural. There are three factors to classifying the park images: nature-harmony, openness, uniqueness. Preferences for each parks are generally good. According to the criteria such as satisfaction of park facility, behavioral satisfaction, images and preference for each park, the 12 parks are divided into 5 different types: multi-purpose park, well-balanced park with natural elements, urban open space, park to be improved, and ecological park. The characteristics of each park was analyzed and categorized. This study dealt with only the parks in Seoul and its environs, and the survey was only done during the summer season. Therefore, further research is necessary to enlarge and generalize the results of this study, considering seasonal and regional variations.

This study was undertaken to investigate the relationship between social support and depression of the elderly in care facilities. We enrolled 328 elderly people aged 65 years or older, admitted to 15 care facilities located in D metropolitan city. Data were collected through personal interviews conducted by interviewers who visited each care facility, from March 1 to May 31, 2018. Our results indicate a significantly higher distribution of depression in the group having lower social support; the score of depression was determined to be in a significant positive correlation with social support. Considering logistic regression, the adjusted odds ratio in the depressed group increased significantly by 2.7 times in the high group (Q3), 5.4 times in the middle group (Q2) and 10.1 times in the low group (Q1), which had the very high group of social support score. Multiple regression analysis revealed that the factors influencing depression include religion status, relationship with children, subjective health status, physical disabilities, smoking status, breakfast status, and social support, and the explanation power of the injected variables is 41.1%. Taken together, our findings indicate that the level of depression amongst the elderly in care facilities is significantly related to the social support available.

In Korea, older pedestrian accounted for 57% of all pedestrian deaths although a ratio of older pedestrian accidents to total pedestrian accidents was only 25.9%. Though ageing population problem becomes more challenging for road safety, little is know about the behaviour of older pedestrian's behaviour. This study aimed to identify road crossing behaviour of older pedestrian at three-lane unsignalized crosswalks using video image analysis and to compare the behaviour of older pedestrian to younger one by indicators including approaching speed, the number of walking steps and other factors. The results showed that there was a difference of approaching time at kerb, waiting time at kerb, the number of glances at kerb, and the number of glances at crossing between two groups under the situation of car approaching to crosswalks. It also showed that older pedestrian usually spent 1.16 times more than younger pedestrian to walk across the crosswalk with only 84.4% of walking speed of younger pedestrian. The number of steps of older pedestrian for road crossing was 1.12 times higher with 90% shorter steps than younger pedestrian. It was concluded that older pedestrian usually decided to walk across in case of 1.67 times longer headway than younger pedestrian's decision. These results could be applied in road and facility design for better safety of older pedestrians.
